[Abstract]:With the development of oil field, the water cut of produced liquid in most oil fields increases rapidly, and the problem of sand production is serious and urgent to be solved. At present, water shutoff and sand control are treated separately in most oilfields, but this method will lead to the increase of production cost, the increase of workload and the serious destruction of formation due to multiple construction. Therefore, before construction, it is necessary to analyze the formation structure, determine the source and physical properties of produced water and sand, select suitable main materials and additives for plugging agent, and optimize the construction process. An integrated technology scheme of profile control, water shutoff and sand control for oilfield production is put forward. In this paper, the present situation and trend of profile control, water shutoff and sand control at home and abroad are summarized. As a key part of the integrated plugging and prevention technology, the plugging method and the selection of the plugging agent are described in detail, and the advantages and disadvantages of each method and the plugging agent are compared, which provides the theoretical basis for the selection of the plugging and preventing agent in different oil fields. With the increasing complexity of oilfield development, the application effect of single plugging agent is obviously decreased. Therefore, the comprehensive use of various plugging agents and construction methods is a hot research topic at present. In this paper, by combining the advantages of plugging control agents, several reasonable optimization models are put forward through a lot of theoretical analysis. In this paper, the main materials and additives of plugging control and control agent are mainly studied in laboratory experiment. The single variable method is used to select drag reducing agent, permeating agent, sand carrying liquid and curing agent, and then the cementing time and compressive strength at different temperature are adopted. Corrosion resistance, aging resistance, permeability, wettability and other factors screening. Select low cost, high physical strength and adjustable cementing time. The effects of water saturation, porosity and sand particle size on effluent and sand production in high water cut reservoirs were studied through laboratory experiments. Combined with the results of laboratory experiments and the field tests in Liaohe Oilfield, the effects of plugging control agents were observed and the results of field tests were followed up and evaluated.
